GILlVI-AN JAQUITH, OF MAYSVILLE, KENTUCKY, ASSIGNOR TO HIMSELF ANDJAhTUARY St WOOD, OF SAME PLAGE.

SPINDLE FOR SPINNING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 264,297, datedSeptember 12, 1882.

Application filed March 22, 1582. (No model.)

To all whom it 'may conce/ru Beit known that I, GILMAN JAQUITH, ofMaysville, in the county of Mason and State of Kentucky, have inventedcertain new and useful Improvements in Spindles for Spinning- Machines,of which the following is a full, clear, and exact description. r

This invention more particularly relates to spindles; and it consists invarious novel constructions and combinations of parts.

The invention also includes a whirl of peculiar construction and variousother details and combinations of details, whereby waste of oil isavoided, the spindle is Wholly inolosed and lint or dust excluded fromit and from mixing with the oil, the whirl is made to form a frictiondriving spool-holder, and numerous other advantages are obtained.

Reference is to be had to the accompanying drawings, formingpart of thisspecilication, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l represents an elevation of an outer tube, whirl, and bobbin,within which the spindle proper is inclosed, the whole representing whatmay be generally termed the spindle,77 which is here shown as applied tothe upper and lower rails of a spinning-frame. Fig. 2 is a longitudinalvertical section of the same. Fig. Sis a transverse section on the line.r min Fig. 2. Figs. et and 5 are sections drawn upon lines run throughFig. 2, the former through lines y y and the latter through lines e z.Fig. 6 is an under view of the Whirl, and Fig. 7 a longitudinal viewotono-half ofa bushing used within the tube in which the lower portionof the spindle proper is inclosed.

ln the drawings, Aindicates a tube arranged to extend through the railsS S of the spindleframe, and with its top, which projects above theupper rail, enlarged to form a cup, b. Screwed into the lower end ofthis tube A is a step-bearing, B, for the spindle O, said'bearingclosing with a shoulder-joint against the bottom end of the tube A, withwhich it makes a tight t to prevent oil from passing out of said tube.

D is a bushing, made with au enlarged upper portion or head, whichscrews into the upper l end of the tube A and rests with a collar bearing on the top of said tube, at the base ofthe cup b. Said bushing isalso made in two longitudinal sections or halves, having perforations cfor supply ot' oil from the tube through them to the spindle, and with alower collar, d, for steadying the bushing within the tube. This collard has one or more passages, e, in it for circulation of the oil, andrests upon a shoulder, c2, formed on the spindle, to prevent the spindlepulling out when being doft'ed. A passage,f, is also formed in the tubeA, on one side ofthe head of the bushing, for establishing a circulationot' oil between the cup b and the tube A, which tube is ofsuiiicientcapacity to keep up a free supply ot' oil to the spindle.

The spindle O, which rests at its lower end in the step-beariiig B, issupported in its upright position by the bushing D.

E represents the whirl on the spindle for driving it, and F is thebobbiu litted over the upper portion ofthe spindle. The whirl E isconstructed to form two reverse cups,g and IL, the lower one, l1., thelatter, ofwhich is inverted. The upper cup, g, constitutes a tapersocket to receive within it the lower taper end of the bobbin,and alsoto form an oil-cup below the bobbin, which, by its entry within the cupg, is driven through friction by said cup or socket g. The lower orinverted cup, h, is constructed to form a free annular tongue-andgroovejoint with the upper edge of the stationary cup b on top of the tube, toprevent oil from passing out from the tube and its cup, within which thespindle rotates. A hole is made through the whirl, which passage iscontinued, as shown at c,into the top ot' thebushing. This hole serves adouble purpose-viz., to form a feed-aperture for the oil from theexterior to the cup b, and from thence down into the reservoir or bodyof the tube A,'aud to admit of the insertion of a key or wire, l, intothe head of the bushing D, to form a handle for holding onto saidbushing when it is necessary to unscrew or remove it by reversing themoforms an enlarged oil-reservoir and serves to hold the step-bearing Band bushing D, which support the spindle, and are not themselvessupported by or brought in contact with the rails.

The cup b, which sits on top of the upper rail, S,forms,in conjunctionwith Athe inverted cup h on the under side of the whirl, a chamber toprevent the possibility of escape of any oil, and also to shutout alllint, dust, or foreign substances which the oil could be absorbed by orbecome mixed with, and so choke the running ofthe spindle.

By the hereinbefore-described manner in which the bushing D is fittedwithin the tube, it, as well as the spindle, (by the shoulder c2 on thespindle below it,) is prevented from being pulled out when doflingbobbins oft' the spin` dle, andthe construct-ion of the body of thebushing, being of a reduced diameter between its upper and lower ends,which tit the tube, leaves a space around the bushing for a freecirculation ofoil, which oil finds ready access to the spindle, thepert'orations in the bushing assisting, and so that the spindle swims,as it were, in oil.

By the concave construction of the under side ofthe whirl E the oilwhich is thrown up by the motion ot'the spindle is received on itsconcavity, and thus caused to liow down into the cup b toward thespindle as a center. This concavity or inverted cup h ofthe whirl hasradial or other suitably-shaped grooves m formed in it, as shown in Fig.6, whereby the regular flow ot' the oil is broken, and as the oilaccumulates in small quantities thereon, it is more readily thrown oft'than it' the iiow were unbroken. The dishing of the upper side ot' thewhirl not only serves to receive within it the lower end ofthe bobbin,and to make said whirl a friction driving` holder ot' the bobbin, but toform an oil-cup, g, for oil to pass into the cup bthrough the hole whichreceives, when required, the key or wire Z, and from which cup the oilpasses, by the continuation of said hole, down into the fixed cup b, andfrom thence on down into the reservoir-chamber ot' the tube A throughthe aperturef.

The advantages of this invention are a great saving of oil, alsoof-labor in cleaning, oiling, and keeping the spindles in good runningorder, less wear and tear ot' the parts, reduced liability to breakageof yarn ends, less waste, anda reduced number ot' bad places in thethread. Another advantage is, that as the spindle always runs in oil,there will invariably be a sufficient amount of oil between the spindleand the bearing to form an elastic cushion, which will serve to destroytremble or jar, and convey an easier motion to the traveler, andconsequently an easier and more unii'orm tension of the thread, therebyreducing the liability to breakage ot the thread.

Having thus fully described my invention,

I claim as new and desire to secure by Letters Patentl. The whirl E,constructed with upper and lower reverse cups, g It, provided with anoilpassage connecting the two cups, substantially as described.

2. The combination, with awhirl,E, having an oil-passage therethrough,of the screwheadcd bushing D, having a hole, 7c, and the tube A, havinga passage,f, betweenit and the head ofthe bushing, as and for thepurpose described.

8. The bushing D, constructed with a screwthreaded head on itsupperend,enlarged lower portion, d, and a reduced perforated waist orbody, substantially as and for the purposes specilied.
